Fluence-independent range of surface roughening within the Gaussian-shaped prole of a low-intensity ultrashort laser
Key Points
This research aims to understand how a Gaussian-shaped ultrashort laser affects surface roughening at the nanoscale.
Irradiated Cu(511) surface with a Gaussian-shaped laser.
Used a low-intensity laser with a duration of 50 femtoseconds.
Analyzed changes in surface morphology post-irradiation.
Observed surface roughening independent of fluence.
Identified effective range of laser impact on surface structure.
Abstract
In the pursuit to master the manipulation of matter at the nanoscale, we investigate the local eects of irradiating a Cu(511) surface with a Gaussian-shaped laser spot lasting 50 fs...
